What open standard allows for the creation of OCI compliant container images?

• A. Image Specification
• B. Runtime Specification
• C. OCI Image Specification
• D. Distribution Specification

Answer: (C)

Open standards from the Open Container Initiative define how container artifacts are built, stored, and used across tools. For creating images that other tools can recognize as OCI-compliant, the defining document is the OCI Image Specification. It lays out the exact structure of an image, including the manifest, config blob, and layers, and specifies the media types and layout that tools like builders, registries, and runtimes expect. This makes image creation portable and interoperable. The runtime specification covers how containers are executed, not how images are formed. The distribution specification deals with pulling and pushing images to registries, i.e., the transport and protocol layer. The term “Image Specification” alone is vague, whereas the OCI Image Specification is the precise standard that governs the image format and creation of OCI-compliant images.
